October 13, 20169 yr Author Oh the joy. I have dropped off my semi re-built engine at a local bike shop who has knowledge of Bultaco's. The owner used to ride them with much success in the 60's Crank has been put into the left hand crank case and there is detectable movement, it seems, in the new bearing ! Getting a little fed up with this..........
October 14, 20169 yr Neil, not a bad plan on the reassembly, you have trans in the LH case as desired, put the spring loaded detent soon. Be sure you rewind the kick shaft 1/2 min turn against the return spring , whoever your friend is knows all this so please excuse me for this preload of the spring, if you have a bearing on the mag side that there is movement, that is rare for me, but any thing is possible. I always use the necessary C3 bearings, usually Japanese KOYO I believe & have very good luck, I have only built 4 this Spring & no problems, so good luck to you at all times. Larry
October 14, 20169 yr Author I'm using KOYO bearings and one of the guys in the shop said he'd had one a while ago that was faulty and had some play so hopefully this will be the answer. I'll find out next week when I'm back.
October 14, 20169 yr Author Wow, they look great. Mine is, and will stay, rough. If it looked that good I wouldn't want to ride it ! I unfortunately won't be in time to enter the Tamar Trial this year but I'll still do the odd one in the chair of my mates Norton 500T
